摘要：

Several new pyrazolo[1,5-a]pyrimidines were synthesized by condensation of 3-amino-1,5-dihydro-1-(p-tosyl)pyrazole 2 with bifunctional reagents. Diazotization of 2 and subsequent coupling with beta -naphthol yielded the corresponding pyrazolo[1,5-c]-as-triazine derivatives. IR and H-1 NMR spectra for all of the hitherto prepared compounds are in good agreement with the proposed structures.
